I know this topic has been touched on before because I have done a search on it. But i have not gotten a really good response or solid information about it. I want to put the best performing and loudest pipes on my bike. I want something that sets car alarms off at idle and gains a good amount of horses. I don't know alot about bikes. But from what I see the 2-1's are the way to go for what I am looking for. Is this correct, Hal, Lamont, Jr, Etc..... ?? I want to look to purchase them soon to put on over the winter here along with some other mod's :evil: (pics when finished). Any help would be appreciated. Trying to do it soon bc I have not really seen any white modded 109's. Also while I have your attention, does anyone know if you have to do cable mods if I put on 2" or 3" risers? Big Joe?
